North Korea is on the verge of obtaining a ballistic missile made by China that can reach Alaska, a senior nuclear analyst told government and military officials Friday morning during a discussion about China’s nuclear prowess.

China has nearly 750 theater and tactical nuclear warheads in addition to more than 200 strategic missile warheads, a stockpile far larger than U.S. estimates, according to a retired Russian general who once led Moscow’s strategic forces.

Law enforcement and national security agencies are investigating the hacking of a White House computer last month that penetrated a network inside the White House Military Office that handles top-secret data, U.S. officials said.
